Re: .exe magic in Cygwin
Sounds like you didn't run autoreconf (which would have been done automatically via the supported mechanism). I have added the autoreconf step to the Emerge scripts. Only one conflicts with a Gentoo patches, which I had to disable. Works fine now. Solved all problems from that corner.

Re: .exe magic in Cygwin
Cygport is rather similar to emerge/ebuild already. You might find it worthwhile to give it a look. I am aware of this. I want come to a solution, that builds me from sources on any of Windows, Mac and Linux. One to rule them all. I did only find Gentoo Prefix to be able to do this. If all you need is a way to install existing Cygwin packages from the command line, you can do that quite well with setup.exe. It has many command line options which help automate the installation process. I hoped so. Probably I will have to use that exessivly to set up the basics. If you want to build a replacement anyway, you should probably delve into why nothing like what you want exists already. This issue comes up repeatedly on this list, so you should be able to find much in the list archives. I found a project called Gentoo on Cygwin. It was abandoned in 2008. http://www.gentoo-wiki.info/HOWTO_Gentoo_on_Cygwin The Gentoo Prefix approach is a little different. It is not a first level, but a second level software manager, completely in the userspace. It sits on it's own prefix as the name tells. It is simply a folder that I can put into any POSIX environment. There is no need to replace all of Cygwin. It is a living project that already works on Mac, Unix and Informix. The missing link is Cygwin.

Re: .exe magic in Cygwin
Right. I applied it the traditional way. Ah, you have to understand this about cygport patches: they only contain patches for the source files, not the autogenerated ones. So they have patches for e.g. Makefile.am, configure.ac; but not for configure or even Makefile.in. It's vitally necessary to autoreconf after applying a patch that you get from a cygport-based package. OK, that's it. As a want to come a hybrid of Cygwin and Gentoos Emerge installer, I rather have to figure out one of those hidden ways. Well, if you're doing it in a POSIX-compatible environment, you should be able to run cygport - with maybe a few minor bugs cropping up, but basically it's just a bunch of shell scripts that invoke the autotools, gcc and binutils, so they should be relatively easy to port to any similar environment. I did once try running cygport on a linux box (with a cross-compiler). I don't remember exactly what went wrong, it didn't work directly out of the box, but it shouldn't be hard to fix. This sounds like a real alternative. Very interesting! It would definitly be worth it's own project group. Then it would be a choice.

.exe magic in Cygwin
Hello, I would like to estimate theexpenses to port general linux sources to Cygwin. I did look into Cygwins patch for coreutils. It has 1231 lines of diff code. A lot of the stuff is related to the .exe magic done by cygwin. Do I have to implement that magic in this extend into every package that I would like to run on Cygwin or is this rather special in the case of coreutils? Thank you for advice Al -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

I first compiled coreutils without the cygwin patch. It did compile but afterwards the compilation of findutils, etc. was broken. For example configure.status of wget was truncated at the top and out of order at the bottom. That stopped all further efforts of mine. Now I applied that big patch. copy.c complaints an error of an undefined reference ot 'cygwin_spelling'. Guess that is a library I have to install.

The only supported way of building coreutils for cygwin is by using setup.exe to download the sources and several prerequisite tools (cygport, autoconf, ...), then using 'cygport coreutils-8.5-1 prep make'. Other ways work, but I won't support them on this list. See also /usr/share/doc/Cygwin/coreutils.README. copy.c complaints an error of an undefined reference ot 'cygwin_spelling'.

It's only the most recent release of cygport (0.10.0) that has rudimentary support for usage on other build environments: 0.10.0: * Added support for building and using cross-compilers. * Experimental support for running cygport on non-Cygwin hosts. IIUC, cygport at best can now be used in the following build vs host situations: cygwin - cygwin other - cygwin cygwin - other I've only tried (1) and (3), not (2). -- Chuck -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
